As a developer, nothing piques my interest more than developer swag! I made devSwag to scratch my own itch by starting a simple list on a GitHub repository (swag-for-dev). I'm excited to share devSwag, THE place to get notified about any new swag opportunities for developers. This would be quite useful this month as Hacktoberfest comes back for the 5th year. If you have any questions or ideas, let me know.
wit.ai is easy to use. You provide some example queries and manually classify training data. Now, every query you give to it returns probabilities of the categories it may belong to. Rinse and repeat.
It provides two tokens; I've included the client side token. :)
